Description

Non-woven end liner and comprise the carpet of this end liner
The present invention relates to comprise through the bonding filament thermoplastic polymer of binder polymer or the non-woven carpet end liner of fiber.
Comprise manufacturing, come out for many years, for example can from United States Patent (USP) 4842915, know through the non-woven carpet end liner of bonding long filament of for example thermoplastic polymer adhesive or fiber.This patent disclosure relates to the nonwoven fabric that is made of polyester matrix type long filament, and this fabric is suitable for the synthetic tuft base cloth make carpet and can be strengthened by the adhesive component with long filament, fiber, powder and/or the fine particle form of softness.This adhesive component is made of than the polypropylene of low 90 ℃ of polyester matrix type long filament or fiber melting range at least melting range.
For many years, in order to satisfy the more and more stricter requirement of manufacturer and consumer, the non-woven carpet end liner constantly is improved.Important improvement is: fracture strength and elongation at break behind the raising synthetic tuft, tear resistance after improving synthetic tuft and being coated with, the general outward appearance that makes carpet of improving, can repair the defective that produces in the synthetic tuft process and make and be easy to synthetic tuft, promptly in the synthetic tuft process, produce the resistance of lower opposing acupuncture, reduce inclined to one side pin, avoid crude back stitch, the noise that increases looped pile bunch and reduce the synthetic tuft process.
An object of the present invention is to reach described improvement.This purpose realizes in the carpet underlay described in first section, wherein end liner comprises the recognizable thermoplasticity weaving layer of one deck at least, one deck thermoplasticity pantostrat or one deck comprise through the bonding long filament of binder polymer or the non-woven layer of fiber, this can distinguish that layer works to reduce the end liner delamination strength, the delamination strength that records according to DIN 54310 reduces at least 30% with respect to not containing the described similar end liner of layer of distinguishing, and preferably at least 50%.
In general, because the acanthopore of synthetic tuft pin can cause break and/or damage, therefore, synthetic tuft can reduce the fracture strength (high initial collapse intensity) of non-woven end liner.And have been found that by (replenish or additional) one deck and can distinguish that layer reaches the reduction of delamination strength that also can reduce the tensile break strength of end liner significantly, the reduction of this intensity looks shortcoming seemingly.Yet this predetermined fracture strength according to the present invention reduces the delamination strength of reduction end liner (promptly by) and has suppressed the fracture strength that causes because of synthetic tuft and the decline of elongation at break.Though the fracture strength according to non-synthetic tuft end liner of the present invention is lower than the non-synthetic tuft end liner of prior art, in fact synthetic tuft end liner according to the present invention has fracture strength and the elongation at break high than prior art synthetic tuft end liner.This phenomenon will be illustrated and confirm by following examples.
Play a part to reduce delamination strength (for example long filament or fiber have than high fluidity and/or low with other layer adhesiveness) on the one hand, the opposing party should have enough laminated cohesive force again so that stand the layer distinguished of (violent) carrying and processing, it can be many different forms, for example dry-laying supatex fabric, wet-laid non-woven fabric or melt-blown fabric.Other example is Woven fabric and pantostrat such as film or paper tinsel.Yet the hot method or the chemical method spunbonded non-woven fabrics that also can carry out acupuncture or Hydroentangled (hydroentangled) are preferred.
